Nepal officials and child rights groups say hundreds of thousands of children have been forced into camps since losing their homes in last month's earthquake and some of them are at risk of exploitation, abuse and even human trafficking.

Namuna Bhusal of the Nepal government's Central Child Welfare Board said Tuesday that the children are exposed to many risks in the camps where people are forced to live together in shared tents and space.

Radio messages have been broadcast warning people not to leave their children without a guardian and to look out for suspicious people in the camps.

The April 25 earthquake killed more than 8,150 people and injured more than 17,860 as it flattened mountain villages and destroyed buildings and archaeological sites.
